One measurement, several readings
Two or three readings, one line
Each measurement collects the readings you add, with their time. You can edit or delete them one by one, and the timeline shows a single line with the average.
Blood Pressure Diary
Your home readings, ready for the cardiologist.
Enter systolic, diastolic and pulse for each reading. Pediary groups them into measurements, works out the morning and evening averages and prepares the PDF to bring to your appointment. For you, for your parents or for a child your doctor needs to follow.

The scrap of paper, and the cardiologist's question
Your doctor asks you to check your blood pressure at home for a week, morning and evening, twice each time. The numbers end up on a scrap of paper, in your phone's notes or in the monitor's memory, and on the day of the appointment you have to put them back in order.
"What was your morning average? Which arm did you use? Was it before or after your medication?"
You don't need a perfect memory: you need one place to write down every reading together with what goes with it.
A diary that does the maths for you
With Pediary you enter readings as you measure. The app keeps them together, works out the averages and prepares a tidy PDF, without ever saying whether a value is good or bad: that is for your doctor to decide.
Features
How the Pediary blood pressure diary works
The app works out the average
Systolic, diastolic and pulse
The average blood pressure of a measurement uses all its readings and updates with every change. You can flag an irregular heartbeat when your monitor shows it: the app records it, it doesn't interpret it.
Morning, afternoon, evening and night
The time of day, which you can correct
The time of day comes from the first reading: night from 0 to 6, morning from 6 to 12, afternoon from 12 to 18, evening from 18 to 24. If you measure right after waking up at 5, you switch it to morning by hand.
Arm, position, context and monitor
How and when you measured
You note the arm, the position and the monitor you used, which stay as last time. Context is chosen each time: rested for 5 minutes, after coffee, stress, before or after medication and more.
The PDF for your cardiologist
Averages, chart and readings
Pick the period and the app prepares a PDF with the morning, evening and whole-period averages, also excluding the first day, the chart, every reading and the medications of the period. You can add your own notes for the cardiologist.
CSV export and medical card
Your data, outside the app too
Export your readings as CSV for a spreadsheet. The emergency medical card shows the average of the last 7 days, with the date of the latest measurement.
Three steps to your blood pressure diary
1
Create the profile
Download Pediary and create an adult profile for yourself or a family member, or use a child's profile: blood pressure is on for every profile and you can turn it off.
2
Enter your readings
From the "+" button choose Blood pressure and enter the first reading, then add the others to the same measurement.
3
Bring the PDF to your appointment
From the blood pressure diary, export the PDF or the CSV for the period and show it to your cardiologist.
Blood pressure diary FAQ
Does Pediary tell me if my blood pressure is high?
No. Pediary shows numbers, averages and charts, but it never says "normal" or "high", doesn't colour values and doesn't draw risk bands. Judging the values is your doctor's job: if you have a doubt, talk to them.
Why several readings in the same measurement?
People who measure at home usually take two or three readings one minute apart, and the doctor looks at the average. Pediary keeps them together in one measurement, works out the average and shows one line instead of three.
What's in the PDF for the cardiologist?
Morning, evening, whole-period and excluding-first-day averages, the highest and lowest value, the day-by-day chart, every reading with time, arm, position and context, the medications of the period with missed doses and, if you want, symptoms, visits from the last 12 months and your own notes.
Does it connect to my monitor?
No, readings are entered by hand. You can note the make and model of your monitor and attach a photo of its display to each measurement.
Can I use it for a family member or a child?
Yes. From version 3.1 you can create adult profiles, for yourself or for someone you care for, and blood pressure is also available on a child's profile. Each profile has its own separate diary.
